Showfilmfirst Erdinger Oktoberfest - London

Got an email through from showfilmfirst for Oktoberfest for this Sunday - I presume a lot of us have received the same? Admin charge of £2 per ticket. Looking at the official site, tickets cost between £5 and £187.50 per person. Its not clear which category of tickets SFF are offering though (I presume its not the top tier, "all drinks included" tickets) - any ideas?
